Lef1 regulates MSC differentiation. A, Transfection efficacy of Lef1 shRNA was confirmed using flow cytometry analysis. B-C, A dose-dependent deletion of Lef1 was detected by RT-PCR (B) and western blot (C). D, Immunofluorescence staining of MSCs transfected with control shRNA and Lef1 shRNA with the primary antibody against α-SMA. E, Representative immunoblots for α-SMA in MSCs transfected with control shRNA and Lef1 shRNA. F, Immunofluorescence staining of MSCs transfected with control shRNA and Lef1 shRNA with the primary antibody against E-cadherin. G, Representative immunoblots for E-Cadherin in MSCs transfected with control shRNA and Lef1 shRNA. Data represent mean ± SEMs of three independent experiments. *P<0.05, **P<0.01.
